OmniGraffle 5.4 shipped in early June with a new set of keyboard shortcuts to zoom in and out of the current canvas. The new shortcuts follow the iWork suite: ⌘> to zoom in, ⌘< to zoom out. This is a deliberate change, but we’ve heard from a few people who’ve suggested other shortcuts — the biggest being the Adobe CS set.

Dr. Drang wrote about keyboard shortcuts in OmniGraffle a year ago, somewhat in the same vein.

But! You can definitely change things around, if you need to, by adding a few Application-specific shortcuts in the Keyboard pane of System Preferences. (In fact, you could add a setting so that any application that has a Zoom In menubar item follows the same shortcut. Caveats: In OmniGraffle and Numbers, ⌘+ is used for making font size larger; other applications might be using it for other things, too.)

Anyway, how’s it done?

Select the Keyboard pane of System Preferences, followed by Keyboard Shortcuts. Select Application Shortcuts in the list on the left.

Click the + button and add Zoom In to the Menu Title field.

Add a shortcut. In this case, to match Adobe’s suite, use ⌘+. (Side note, this is actually, of course, ⌘=. As far as I can tell, OS X won’t ever show + in place of =, even with ⇧.)

Do the same thing (+ button, Zoom Out, and add ⌘–) for zooming out.

You’re done! If you’d like that to be global, leave “Any Application” in place.

Hopefully you’re all enjoying Mountain Lion! Here’s to the early adopters.
